ln(x^2+1)=a

Solution

ln (x^{2} + 1) = a

Solution

x = e^{a} - 1, x = - e^{a} - 1

Solution steps

ln (x^{2} + 1) = a

Apply log rules

x^{2} + 1 = e^{a}

Solve

x^{2} + 1 = e^{a} : x = e^{a} - 1, x = - e^{a} - 1

x = e^{a} - 1, x = - e^{a} - 1

Popular Examples

log_{4}(256)+log_{s}(16)=6

lo g_{4} (256) + lo g_{s} (16) = 6

ln(x)=-2ln(1/3)

ln (x) = - 2 ln (\frac{1}{3})

log_{120000}(x)=160000

lo g_{120000} (x) = 160000

2log_{3}(6)+log_{3}(y)=4

2 lo g_{3} (6) + lo g_{3} (y) = 4

ln(x+1)-ln(3)=3

ln (x + 1) - ln (3) = 3
